This double limiting form has a better force effect and the electrical cabinet operating handle has high reliability.

[0010] The control panel is used to be connected with the square rod, and the control panel and the square rod can be driven to rotate synchronously by turning the handle.

[0011] In one embodiment of the present invention, the arc groove has a first end and a second end, there are two limit blocks, which are respectively arranged on two side walls of the arc groove, and the electrical cabinet operating handle also includes a release spring, one end of the release spring abuts against the first end, and the other end abuts against the limit block, the arc portion has a limit step, and the limit step divides the arc portion into a small size portion and a large size portion.

[0046] The present invention is described in detail below in conjunction with the accompanying drawings.

[0047] Example 1

[0048] like Figures 1 to 7 As shown, an electrical cabinet operating handle (also called a self-resetting shunt trip operating handle) includes:

[0049] A hollow base 1, a first surface 2 of the base 1 having an arc groove 3, a side wall of the arc groove 3 having a limit block 4, and a second surface 5 of the base 1 having two limit bosses, namely a first limit boss 6 and a second limit boss 7;

[0050] A handle 8 has a rotating portion 9 passing through the base 1, and the handle 8 also has an arc-shaped portion 10 extending into the arc-shaped groove 3;

[0051] The control panel 11 is located on the second surface 5 of the base 1 and is fixed to the rotating part 9. The control panel 11 has a protrusion 12, and the limiting boss is used to cooperate with the protrusion 12 to limit the rotation stroke of the control panel 11; the handle 8 has a first extreme position and a second extreme position. In the first extreme position, the protrusion 12 abuts against the first limiting boss 6, and the arc portion 10 abuts against the limiting block 4; in the second extreme position, the protrusion 12 abuts against the second limiting boss 7, and the arc portion 10 abuts against the end of the arc groove 3.

[0052] In the electrical cabinet operating handle of the present application, the rotational travel of the handle 8 is limited not only by the limiting boss, but also by the limiting block 4 and the arc groove 3. This double limiting form has a better force effect and the electrical cabinet operating handle has high reliability.

[0053] When in use, the control panel 11 is used to be connected to the square rod, and the control panel 11 and the square rod can be driven to rotate synchronously by rotating the handle 8.

[0054] like Figure 6 As shown, in this embodiment, the arc groove 3 has a first end 13 and a second end 14, there are two limit blocks 4, which are respectively arranged on the two side walls of the arc groove 3, and the electrical cabinet operating handle also includes a release spring 15, one end of the release spring 15 abuts against the first end 13, and the other end abuts against the limit block 4, the arc portion 10 has a limit step 16, and the limit step 16 divides the arc portion 10 into a small size portion 17 and a large size portion 18. When in the first extreme position, the small size portion 17 passes through the gap between the two limit blocks 4, compresses the release spring 15, and the limit step 16 abuts against the limit block 4. When in the second extreme position, the large size portion 18 abuts against the second end 14;

[0055] The handle 8 has an elastic positioning pin 19 , and the first surface 2 has a positioning groove 20 . The elastic positioning pin 19 is used to cooperate with the positioning groove 20 to achieve positioning.

[0056] Because the release spring 15 is provided, after the handle 8 is rotated to the first limit position and released, the handle 8 can be rotated a certain distance in the opposite direction under the action of the release spring 15 until the elastic positioning pin 19 cooperates with the corresponding positioning groove 20, and automatic positioning is achieved by hearing a click.

[0057] like Figure 6 As shown, in this embodiment, the handle 8 has a plurality of working positions, and there are also a plurality of positioning grooves 20, one corresponding to each working position.

[0058] like Figure 5 and 7 As shown, in this embodiment, the elastic positioning pin 19 includes a first pin 21 and a first spring 22 for pushing the first pin 21 to move toward the first surface 2 .

[0059] like Figure 1 and 7 As shown, in this embodiment, the first surface 2 has a fixing hole 23, the handle 8 has a slide groove 24, the side wall of the slide groove 24 has a plurality of first locking holes 25, and the handle 8 is also equipped with a fixing pin assembly 26 and a push plate 27 slidably installed on the slide groove 24, the push plate 27 has a second locking hole 28, and the push plate 27 has a first working position and a second working position. In the first working position, the push plate 27 covers all the first locking holes 25. In the second working position, after the push plate 27 slides, it no longer covers the first locking hole 25, and the axis of the second locking hole 28 coincides with the axis of the corresponding first locking hole 25, and the push plate 27 drives the fixing pin assembly 26 to move toward the first surface 2 and extend into the corresponding fixing hole 23, so that the handle 8 and the base 1 are fixed in the circumferential direction.

[0060] The design of the multiple first lock holes 25 allows multiple locks to be hung, so that the function of requiring multiple people to unlock the handle 8 to control the rotation can be realized.

[0061] like Figure 5 and 7 As shown, in this embodiment, the fixing pin assembly 26 includes:

[0062] A second pin 29 is slidably disposed in the handle 8;

[0063] A support sheet 30, located between the handle 8 and the first surface 2, the support sheet 30 having a through hole 36 for the second pin 29 to pass through;

[0064] The second spring 31 is sleeved on the second pin 29 , one end of which abuts against the support sheet 30 , and the other end of which is used to push the second pin 29 to move to a side away from the support sheet 30 .

[0070] A handle 8 having a rotating portion 9 passing through the base 1, and the handle 8 also having a protrusion 40 extending into the first surface 2 of the base 1;

[0071] The control panel 11 is located on the second surface 5 of the base 1 and is fixed to the rotating part 9. The control panel 11 has a protrusion 12, and the limiting boss is used to cooperate with the protrusion 12 to limit the rotation stroke of the control panel 11; the handle 8 has a first extreme position and a second extreme position.

This double limiting form has a better force effect and the electrical cabinet operating handle has strong reliability.

[0073] In this embodiment, the first surface 2 of the base 1 has an arc-shaped limit block 39, and the two end surfaces of the arc-shaped limit block 39 are respectively the first limit end surface 37 and the second limit end surface 38. In other embodiments, two limit blocks 4 may be provided.
